Table 2

Mean (SD) 25OHD, calcium, adiponectin, and insulin concentrations of the women with PCOS and their control group.

Parameter	PCOS group (𝑛∶103)	Control group (𝑛∶103)	𝑃 value
Insulin (pmol/L)	80.5 ± 62.5	53.4 ± 29.8	0.004
HOMA index	2.3 ± 1.9	1.5 ± 0.9	0.007
Adiponectin (ng/mL)	8.4 ± 2.7	13.6 ± 5	<0.001
Calcium (mmol/L)	2 ± 0.1	2.55 ± 0.17	<0.001
25OHD (nmol/L)	30 ± 2.99	43.7 ± 5.2	<0.001

HOMA index: homeostasis model assessment index; 25OHD: 25 hydroxy vitamin D.
